Choosing a DNS Server for your home network or home lab environment is crucial to performance and security. There are many public DNS servers that can be used for DNS queries. However, in this post, we will look at the best DNS server you can self-host, with five options for the best features, security, and performance.

Selecting the Best DNS Servers

When searching for the best DNS servers, several factors come into play. These include the server’s ability to manage DNS queries efficiently, its compatibility with different IP addresses, and their ability to implement secure DNS services. Also, in addition to running a firewall, DNS servers can provide controls in blocking malicious websites and phishing sites, spyware, and other threats, in addition to content filtering for kids is important.

Many well-known public DNS servers exist for lookups, from well-known options like Google DNS, OpenDNS, quad9, and Cloudflare DNS to more specialized services like Comodo Secure DNS, or even the default DNS servers from your ISP as an option. These are great DNS options for systems as they have protection built in from things like DDoS, cyberattacks, and other threats. 

However, in addition to these public DNS providers, let’s dive into the best free DNS service solutions you can self-host in your home network or home lab environment and the features of each. Note the following example solutions in the list:

  1. Technitium

The Role of DNS in Internet Connectivity

DNS servers are the “phone book” of the Internet and translate the human-readable domain names that we can remember to the underlying IP addresses that are not easy to remember. When you open a browser and type in the name of a site on a PC, Android or iPhone, PS4, computer, etc, whether you are on a LAN or Wi-Fi connection, your DNS server looks up the name and translates it to the IP that your device can use to connect to the web server or other resource, locally, or across the world.

Understanding the impact of DNS servers on Internet connection is key. It does make a difference which DNS server addresses you configure in your network connection. Not all free DNS servers are created equal. Where do you configure DNS settings? Below, we see the IPv4 properties in Windows 11 (or IPv6). If you look at the General tab, you will see the primary and secondary DNS servers you can configure. Having two servers configured is the best way as it helps ensure uptime and everything is reachable, in case primary server is down or unreachable. Keep in mind these are not used for load balancing per se, but failover.

Why DNS Caching is Key to Performance

One of primary advantages with running your own DNS server at home is the ability to cache DNS queries. So, instead of your devices reaching out to the Internet for a DNS hostname and resolving that to an IP address, you bring that exchange local to your home network. Many routers and other commodity network devices may also cache queries, but they don’t provide the features and capabilities of the solutions we have covered.

With DNS caching, queries are stored temporarily which reduces the need to repeatedly resolve the same domain names. This process speeds up website loading times due to faster name resolution.

Once a DNS server caches a domain name, further requests for that domain can be answered quickly, bypassing the process of querying multiple DNS servers. This accelerates web page access and reduces the load on DNS servers. This makes the overall DNS name resolution process more efficient. Note the following tests I performed with DNS Benchmark.

Below you can see the DNS Benchmark (dnsperf) used shows the latency and speed of the DNS servers. The first IP address in the list is my local caching DNS server that I have configured and is handed out by my router to clients. You can see the relative speed of all the rest. This directly impacts games, apps, and all other connections.

Now, you can see the difference in a public DNS server and the latency between the query results. For cached queries it is about 26 milliseconds and 79 milliseconds for uncached.

Frequently Asked Questions About DNS Servers

How does a DNS server improve my internet security? 

DNS servers improve Internet security by filtering malicious domains and blocking access to phishing sites, spyware, etc. Some DNS providers offer advanced security features like web filtering. Web filters can block adult content and malicious websites, which helps to protect your online activities.

Can free DNS services match the performance of paid ones?

Many free DNS services, such as Google Public DNS or Cloudflare DNS, offer comparable, if not superior, performance to paid DNS providers. They often include features like fast dns servers, efficient handling of dns queries, and support for dynamic dns.

Why is it important to have both primary and secondary DNS servers? 

Primary and secondary DNS servers provide redundancy and reliability. If the primary DNS server fails or experiences issues, the secondary server takes over, ensuring continuous internet access and efficient handling of DNS requests.

What makes for a “fast” DNS server? 

A fast DNS server depends on many factors. These include the server’s response time, latency, and its ability to handle DNS data and requests. Hosting your DNS server locally will eliminate the need for clients to make DNS requests over the Internet and can instead have their queries answered locally.

Is it difficult to switch to a different DNS provider? 

Switching to a different DNS provider is generally straightforward. It involves changing the DNS server addresses in your network settings. Most DNS providers offer clear instructions for this process, making it accessible for users with varying levels of technical expertise.

Does a self-hosted DNS server offer better control over DNS settings? 

Absolutely. A self-hosted DNS server, like PiHole with Unbound, gives users full control over their DNS settings. This allows for customization of dns server addresses, management of domain names, and the ability to tailor dns data handling according to specific needs, such as blocking ads or prioritizing security.

Can a DNS server affect the handling of IP addresses for a local network? 

Yes, some DNS servers provide dynamic DNS support, which is essential for networks with changing IP addresses. This feature ensures that the domain names in your network always correspond to the correct, current IP addresses, enhancing the reliability of your internet activity.

How does a secondary DNS server improve DNS reliability?

A secondary DNS server acts as a backup, ensuring that dns requests are consistently resolved even if the primary server is down. This redundancy is crucial for maintaining uninterrupted access to web pages and ensuring consistent internet performance.

Wrapping up Best DNS Server for your needs

The DNS server is critical to any network, including your home network or home lab environment. While there are many great public DNS servers, having your own self-hosted DNS server provides advantages. You can benefit from the super fast speed of cached queries accessible from your LAN and reduce the number of outbound DNS connections to the Internet. This can provide noticeable improvements for gaming, self-hosting, application response, and other use cases. The five solutions I mentioned in the post are some of today’s best solutions. However, no matter which one you try, they will all greatly benefit your home Internet experience and help keep your environment safe.
